Process for preparing surfactant mixtures having high solids content

Abstract

Highly concentrated mixtures of surfactants are obtained by a method which comprises adding the acid form of a neutralizable surfactant to an aqueous composition comprised of a base and an alkyl polyglycoside.

What is claimed is: 
     
       1. A composition consisting essentially of: (a) water, (b) from about 25% to about 40% by weight of the sodium salt of an anionic surfactant selected from the group consisting of: an alkyl isethionate, an alkyl sarcosinate, a sulfosuccinate, an alkyl taurate, an olefin sulfonate, and a mixture thereof and, (c) from about 25% to about 40% by weight of a compound of the formula   R.sub.1 O(Z).sub.a                                         I     wherein R 1  is a monovalent organic radical having from about 6 to about 30 carbon atoms; Z is a saccharide residue having 5 or 6 carbon atoms; a is a number having a value from 1 to about 6, wherein the composition is in the form of a concentrated solution.   
     
     
       2. The composition of claim 1 wherein said compound of formula I is a C 8-16  alkyl polyglycoside. 
     
     
       3. The composition of claim 1 wherein said compound of formula I is a C 12-16  alkyl polyglycoside. 
     
     
       4. The composition of claim 1 wherein said compound of formula I is a C 12-16  alkyl polyglycoside having an average degree of polymerization of 1.4. 
     
     
       5. A composition consisting essentially of: (a) water, (b) from about 25% to about 40% by weight of the sodium salt of a neutralized protein-fatty acid condensate and, (c) from about 25 % to about 40% by weight of a C 8-16  alkyl polyglycoside, wherein the composition is in the form of a concentrated solution. 
     
     
       6. A composition consisting essentially of: (a) water, (b) from about 25% to about 40% by weight of the sodium salt of a neutralized protein-fatty acid condensate and, (c) from about 25% to about 40% by weight of a C 12-16  alkyl polyglycoside, wherein the composition is in the form of a concentrated solution. 
     
     
       7. A composition consisting essentially of: (a) water, (b) from about 25 % to about 40% by weight of the sodium salt of the neutralized protein-fatty acid condensate and, (c) from about 25% to about 40% by weight of a C 12-16  alkyl polyglycoside having an average degree of polymerization of 1.4, wherein the composition is in the form of a concentrated solution. 
     
     
       8. A composition consisting essentially of: (a) water, (b) from about 25% to about 40% by weight of the sodium salt of a neutralized protein-fatty acid condensate and, (c) from about 25 % to about 40% by weight of a mixture comprising a C 8-16  alkyl polyglycoside and a C 12-16  alkyl polyglycoside, wherein the composition is in the form of a concentrated solution.
